more like that of the Felidae than of the 'ViveTridcue, and the
teeth are more Feline in structure. The claws of the feet are
retractile. As to internal structure the Fossa agrees largely
with the "Viverridae, but then this family has no very marked
points of difference from, the Felidae; but where the anatomy
does diverge from that of the Felidae it approaches the "Viverridae,
especially in the musculir system.

The remaining and by far the larger number of genera of
Civets are grouped by Professor Mivart in two sub-families :
the ViVERRiisrAE, including the genera Viverra, Viverricula,
Fossa, G-enetta, JPrionodon, JPoiana, Paradoxurvis, Arctogale,
JTemigale, -Arctictis, JWandinia,, and Cynogale ; and the HERPES-
XIKAE, including the genera Iferpestes, Selogcde, Cynictis, and
probably Bdeogale and JShyncJiogale. In the "Viverrinae the
digits are always five, the claws are more or less retractile, the
prescrotal scent glands are usually present, and the anus does
not open into a sac. On the other hand, the Herpestinae are
characterised by the non-retractility of the claws, the absence of
the glands in question, and the fact that the anus does open into
a terminal sac.
Sub-Fam. 4. VIverrinae, - Viverra includes the true Civets.
The genus, save for one African species, is Oriental in range.
The molar formula is the complete one for the Viverridae, viz.
